Abstract

MXene aerogel become promising electrode material for supercapacitors because of excellent conductivity and processability, but scalable synthesis of MXene aerogel still face great challenge. The study reports synthesis of Ti3C2TX...

Facile synthesis of Ti3C2Tx@gold nanoparticle-arginine and serine-functionalized graphene quantum dot aerogel for electrochemical detection of chloramphenicol

“…These factors reduce the intensity of the diffraction peak of graphene at 26°. 21 The peaks at 38.43°, 44.67°, 65.07°, 78.10° and 82.07° correspond to the (111), (200), (220), (311) and (222) facets of the fcc gold nanocrystal (no. JCPDS 4-0784).…”

“…AS-GQDs were prepared using a previously reported method. 21 Typically, 1.0 g of citric acid, 0.5 g of arginine and 0.8 g of serine were dissolved in 20 mL of ultrapure water. The solution was heated at 95 °C with mechanical stirring until all free water was removed.…”

Current Trends and Promising Electrode Materials in Micro-Supercapacitor Printing

“…chalcogenide [195,196] and carbon nanoparticles [197], layered double and triple metal hydroxides [198], and other components (Figure 9). This can lead not only to an increase in basic properties (as a result of the formation of three-dimensional structure and heterojunctions), but also due to the synergetic effect to the emergence of new useful qualities, for example, the expansion of the temperature range of application of supercapacitors on their basis both in the direction of high and low temperatures, to an increase in mechanical strength to stretching, impact, etc.…”

“…Overall, the current vigorous work on finding ways to improve the stability of MXenes in aqueous dispersions opens up prospects for designing more environmentally friendly production of energy storage devices in the future. Furthermore, there is a huge body of research devoted to the study of the effectiveness of improving the characteristics of such devices as a result of the use of composites, for example, with the addition of electrically conductive polymers [ 193 , 194 ], semiconducting oxide, chalcogenide [ 195 , 196 ] and carbon nanoparticles [ 197 ], layered double and triple metal hydroxides [ 198 ], and other components ( Figure 9 ). This can lead not only to an increase in basic properties (as a result of the formation of three-dimensional structure and heterojunctions), but also due to the synergetic effect to the emergence of new useful qualities, for example, the expansion of the temperature range of application of supercapacitors on their basis both in the direction of high and low temperatures, to an increase in mechanical strength to stretching, impact, etc.…”

Recent Advances and Strategies in MXene-Based Electrodes for Supercapacitors: Applications, Challenges and Future Prospects

“…Numerous MXene phases have been reported, including Ti 3 C 2 T x [ 49 ], Ti 2 CT x [ 50 ], Nb 2 CT x [ 51 ], Nb 4 C 3 T x [ 52 ], Mo 2 C [ 53 ], V 2 CT x [ 54 ], among others. Of these phases, Ti 3 C 2 T x is commonly studied due to its superior intercalation pseudocapacitance behavior and electronic conductivity [ 55 ].…”
